Insulated puncture resistant inflatable mattress
First Claim
1. An inflatable enclosure having first and second broad surfaces connected at their edges to form the enclosure, the first surface being formed of a substantially air-impermeable resilient closed-cell foam wherein the thickness and density of the closed-cell foam has been selected to provide semi-rigid characteristics between adjacent points of support and the second surface being formed of material selected from an air-impermeable resilient closed-cell foams and a flexible air-impervious material, said first surface being connected around its edges to a flexible air-impervious material which is in turn attached around the edges of the second surface to form the enclosure, the enclosure having at least one closable means for admitting a fluid to and releasing fluid from the enclosure.

Abstract
An inflatable enclosure useful as a matress is described which has first (bottom) and second (top) broad surfaces connected at their edges to form the enclosure, the bottom being formed of a substantially air-impermeable resilient closed-cell foam wherein the thickness and density of the closed-cell foam has been selected to provide semi-rigid characteristics between adjacent points of support and the top being formed of material selected from an air-impermeable resilient closed-cell foam and a flexible air-impervious material, said first surface being connected around its edges to a flexible air-impervious material which is in turn attached around the edges of the second surface to form the enclosure, the enclosure having at least one closable means for admitting a fluid to and releasing fluid from the enclosure.

6. An inflatable enclosure having first and second broad surfaces connected at their edges to form the enclosure the first surface being formed of a substantially air-impermeable resilient closed-cell foam wherein the thickness and density of the closed-cell foam has been selected to provide semi-rigid characteristics between adjacent points of support and the second surface being formed of material selected from an air-impermeable resilient closed-cell foam and a flexible air-impervious material, said first surface being connected around its edges to a flexible air-impervious material which is in turn attached around the edges of the second surface to form the enclosure, said enclosure containing a plurality of compressible resilient units attached to opposite points of the inside of the first surface and the inside of the second surface of the enclosure
(a) to cause self-inflation of the enclosure when air or another fluid is admitted to the collapsed enclosure; - and
(b) to substantially reduce billowing when a weight is placed on the inflated enclosure; the enclosure having at least one closable means for admitting a fluid to and releasing fluid from the enclosure. - View Dependent Claims (7, 8, 9, 10, 11, 12)
